IMPROVEMENT IN ADJUSTABLE CHIMVNEV-CAPS.`

Specification forming part of Letters Patent No. 132,249, dated October15, 1872.

l To all -whom it may concern:

Be it known that I, PATRICK H. GARLIN, of Brooklyn, in the county ofKings and State of New York, have invented a new and ImprovedOhimney-Cap, of which the following is a specification: d

Figure lis a vertical longitudinal section of my improved chimney-cap.Fig. 2 is a bottom View of the same.

Similar letters of reference indicate corresponding parts.

This invention has for its object to produce a metallic chimney-cap orcovering for the tops of chimneys in place of the blue-stone or otherstone or brick caps heretofore used, and thereby to increase thestrength and durability of chimneys, and reduce the possibility of theircrumbling to pieces. The invention consists in the use of a metallic tophaving adjustable ledges to iit any thickness of walls,

. and adjustable cross-pieces to tit any position of iiues, ashereinafter more fully described.

A in the drawing represents a plate of cast metal with a pendent an ge,a., around its edge. This plate, of the shape of the chimney to becovered, is slightly larger than the chimney, so that the flan ge a willembrace and fit the outer face thereof, as shown in Fig. l.

The inner portion of the plate is open to allow the smoke to escapethrou ghthe iiues, and is provided with cross-pieces B B, which coverthe walls between the iiues. These cross-pieces are, with their ends,fitted in grooves ou the inner edges of the perforated plate A, and cantherein be adjusted more or less laterally, so as to cover the wallsbetween the hues in whatever position they may be. The adjustment of theplatesB, and their support on the plate A, may also be obtained by othermeans, such as by slots in B and pins on A, or otherwise. The plate Amay also be divided longitudinally across its opening when there are twoor more rows of ues in the chimney which are to be covered. -To theunder si'de of the plate A are fastened, by means of slotted ears b b,pendent plates, which are parallel with the sideand end angesa a.. Thesependent plateslap against-the inner facesof the outer chimney-walls, asshown in Fig. 1, and serve, together with the anges a .to secure the capin placeon the chimney. The adjustability of these pendent plates C onthe plate A is necessary on account of the varying thickness of thechimney-walls, which are hardly ever exactly alike.

- I proposeto'manuiacture plates A of the kind above described, orsubstantially like it, in varying sizes and shapes, to suit and fit thechimneys most commonlymade, so that the builders can, from an assortmentof such plates, pick out those which will fit the chimneys of theirhouses.

The invention is applicable not only to new chimneys but to thosealready in use. At

present the chimney-caps are made of stone, and perforated to admit thesmoke through the lues. 4Such stones are very costly, owing to themanual labor required in their formation. If made cheaper by beingcomposed of several parts they are apt to crumble to pieces, owing tothe destructibility of the cement used in joining the pieces.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The plate A, provided with the flanges a and theadjustable pendent plates C, as set forth. t

2. The adjustable plates B B, arranged within the metallic chimney-capA, substantially as and for the purpose herein shown and described. 'f
